TOP-ROLL SADDLE.

Specification il ts a Patented June 10, 1919.

Application filed August 21, 1918. Serial No. 250,855.

To all whom it may concern:

Be it known that I, EZRA DIXON, a citizen of the United States, residingat Bristol, in the county of Bristol and State of Rhode Island, haveinvented a new and useful Improvement in Top-Roll Saddles, of which thefollowing is a specification.

This invention relates to certain new and useful improvements in toproll saddles, and the primary object thereof is to provide means ofconnection between the front and back saddles, which will require thatthe saddles be first held in angular relation and then be relativelyrotated, in order to connect and disconnect the saddles so as to alterthe position of the back saddle.

The invention in brief proposes to provide a worm-like connectionbetween the two saddles, necessitating that the latter be held in aslight angular relation and then a number of rotations impartedpreferably to they front saddle in order to connect and disconnect same,to thereby enable the position of the back saddle to be altered orreversed.

In the drawings 1 Figure 1 is a side elevation of the inven tion partlybroken away and in section, and applied to a spinning machine, thelatter being shown in fragment.

Fig. 2 is a top plan view of the two saddles, and

Fig. 3 is a rear end elevation.

In proceeding in accordance with the present invention, the front saddle1 which rides on the front roll 2 is formed with a rearwardly extendingshank 3 terminating in a worm, spiral, or gimlet-like part 4, the latterextending in offset relation to the bottom of the shank 3.

The back saddle 5 is adapted to ride either on the back roll 6 or themiddle roll 7 and has suitable roll straddling means 7 on its bottom andon its top is provided with an upstanding arm 8 which latter isperforated or apertured at 9. The circular wall resulting from theperforation 9 is smooth and unthreaded.

In connecting the saddles the latter are held in substantially theangular position shown in dotted lines in Fig. 1, and then worm orgimlet has its pointed or free end 10 introduced in the aperture 9 ofarm 8 following which the front saddle is rotated causing the worm tomove through the apsmooth and unthreaded it will be apparent that thegimlet or worm may be easily passed through the aperture and in additionthere are no threads subject to being stripped or mashed. The wormitself is relatively large and its convolutions are not subject to beingstripped or mashed. The diameter of the gimlet or worm is greater thanthat of the aperture 9, which necessitates the angular relation of theparts above mentioned in connecting the same, and which assures theparts being held against accidental separation when in the full lineposition shown in the drawings.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is- 1. In a top roll saddle, a front saddle anda back saddle, said front saddle having a rearwardly extending shankprovided with a worm or gimlet-like terminal, and an apertured arm borneby the back saddle to receive said worm or gimlet-like terminal andhaving its said aperture of less diameter than that of the worm orgimlet-like terminal and the walls defining the aperture smooth.

2. In a top roll saddle, a front saddle and a back saddle, an aperturedarm borne by the back saddle, and a worm or gimlet-like part on thefront saddle engageable in the aperture of the arm.

3. In a top roll saddle, a front saddle and a back saddle, an aperturedarm borne by the back saddle, and a worm or gimlet-like part on thefront saddle engageable in the aperture of the arm, said aperture havingits defining wall smooth.

In a top roll saddle, a front saddle and a back saddle, an aperturedmember borne by one saddle and having the wall defining a back saddle,and connecting means bename to this specification in the presence tweenthe saddles formed so as to requlre of two subscrlbmg wltnesses.relatlve angular posrtlonlng of the saddles and then a number ofrotations of one sad- EZRA DILON' dle With respect to the other toconnect and WVitnesses: V disconnect same.
